Rhadamanthys

Actor(s): Sandworm

VTCollection

According to PCrisk, Rhadamanthys is a stealer-type malware, and as its name implies - it is designed to extract data from infected machines.

At the time of writing, this malware is spread through malicious websites mirroring those of genuine software such as AnyDesk, Zoom, Notepad++, and others. Rhadamanthys is downloaded alongside the real program, thus diminishing immediate user suspicion. These sites were promoted through Google ads, which superseded the legitimate search results on the Google search engine.
